Total number of harvested leaves was the highest in control with 14, which followed by KCI 2 me/L and CaCl©ü1 me/L. Nitrate content was decreased by addition of chloride in nutrient solution. Nitrate content in the 3rd and 9th leaves was significantly decreased. NR activity was higher in control and CaCl©ü addition treatments, while KCI addition treatments reduced NR activity. However, no direct relationship with nitrate was observed. Growth characteristics such leaf length and leaf width were not significantly influenced by chloride addition. |

| Di-(2-ethylhexyl) phthalate (DEHP) is a plasticizer known as one of endocrine disruptors. The present study was carried out to investigate the alterations of function and ultrastructure in rat testes after oral intubation of DEHP in dosages of 1g/kg/day, 2 g/kg/day or 3 g/kg/day in 0.5 ml of corn oil for 15 days. DEHP reduced the growth of body and testes, inhibited apermatogenesis and induced structural changes on various cell types of the rat testis. Leydig cells, Sertoli cells and the developing germ cells seemed to be impaired their differentiations in terms of the structural changes of cell organelles. The increase of heterochromatin in amount were common features in all 3 cell types. In addition, the Leydig cells were characterized by the swelling of smooth endoplasmic reticulum and perinuclear space, the increases in number and size of Iysosomes. The Sertoli cells became irregular in nuclear envelope and the number of Iysosomes and vacuoles seemed to be increased. There were some indications of necrosis of the germ cells, such as vacuolized nucleus and segregated nucleolus. And also, DEHP lowered the level of testosterone in experimental rat serum. DEHP suppressed apermatogenesis decreasing developing germ cells and these effects of DEHP on the rat testis were dose dependent. The detrimental effect of DEHP on apermatogenesis and ultrastructure of rat testes seems to be derived from the decreased level of testosterone by Leydig cells, followed by the abnomalities of Sertoli cells and the germ cells. |
